Among the “enforecement action” taken by the FDA, the agency has sent a warning to the American Cellular Laboratories Inc., which sells many of the supplements, including TREN-Xtreme, MASS Xtreme, ESTRO Xtreme, AH-89-Xtreme, HMG Xtreme, MMA-3 Xtreme, VNS-9 Xtreme, and TT-40-Xtreme. The FDA has stated that these products are unapproved, ineffective, and dangerous to consume. As such, the FDA recommends that everyone stop using the defective products immediately – and to see and doctor and report adverse effects if they have been injured by one of the products. Many of the products were sold at gyms, sporting events, and on the internet.

The FDA also engaged in a federal raid on the California home of American Cellular Labs CEO Maurice Sandoval and an affiliate supplement store Max Muscle in order to collect information about the business’ practices.

“The FDA has received reports of serious adverse events associated with the use of these products and other similar products. Products like these are frequently marketed as alternatives to anabolic steroids for increasing muscle mass and strength and are sold both online and in retail stores. They are often promoted to athletes to improve sports performance and to aid in recovery from training and sporting events,” said the FDA’s health advisory.

These defective products have led to liver failure, liver injury, and other health problems in at least 15 different reported cases.

The body building dietary supplement company will have two weeks to respond to the warning letter sent to them by the FDA. Their response should list the corrective measures they plan to take in order to continue distributing products to the public.
